Document Type and Number:
Japanese Patent JP2018008619
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pneumatic tire comprising a partial rubber layer selectively located on a part of an interlayer between a carcass layer and an inner liner layer, maintaining braking performance on a dry road surface, and enabled to be reduced in tire weight and rolling resistance.SOLUTION: In a pneumatic tire, an inner tie rubber layer 11 and an outer tie rubber layer 12 are respectively selectively located in areas on tire width direction both sides each of which is between a carcass layer 4 and an inner liner layer 9 excluding a center region of a tread part 1, ends of the inner tie rubber layer 11 and the outer tie rubber layer 12 on a tire equator side are respectively located within a range of 0 mm to 15 mm from an end of a belt layer 7 on a tire width direction outermost side to a tire width direction inner side, a rubber thickness of the inner tie rubber layer 11 is differed from a rubber thickness of the outer tie rubber layer 12, and a rubber thickness t1 of the inner tie rubber layer 11 is made to be 120% to 200% of a rubber thickness t2 of the outer tie rubber layer 12.SELECTED DRAWING: Figure 1
